Buttered fly

Not to be confused with Butterfly.

A buttered fly is a paradoxical insect, as if a fly is buttered, it cannot fly. Buttered flies are trapped by the Kernel-pult's buttery projectiles as a useful way for it to catch prey, combining the precision of a bladderwort and the stickiness of a cobweb.
